The 5 c.c. 
plate revolves 
about 11% 
faster with 2 jets. 
,, 10 c.c. 
.. 24% 
All machines are fitted with 2 removable jets, one of which can be blocked up if desired. 
All removable parts, such as the revolving plates, spindles, etc., are carefully made to standard, and are therefore 
interchangeable. 
When erecting, place thick rubber pads under the screw holes. It is important to see that the spindle is truly vertical : 
if the bench is fairly level, this can be done by placing a spirit level upon the plate, and varying the tension on the screw's 
until it is horizontal. 
The spindle should be just loose in its bearings to secure the best speeds. 
PLATE FOR ALBUMINOMETERS.—A special Plate to fit in the Martin Water-Driven Centrifuge 
(Palmer Type), can now be supplied to take four Aufrecht Albuminometers. Owing to the larger size 
of the plate, the speed, for a given water pressure, will not be quite so high as with the Standard Plates,
